Vinyl records, with their rich analog sound, have experienced a resurgence in popularity in recent years. If you’re one of the many people rediscovering the joys of vinyl, you might be wondering if it’s possible to connect a turntable to an auxiliary (AUX) input on your audio equipment. In this article, we’ll explore the possibilities and considerations involved in connecting a turntable to an AUX input.
Understanding Turntable Outputs
Before attempting to connect a turntable to an AUX input, it’s essential to understand the output signals produced by a typical turntable. Turntables generally have two types of outputs:
- Phono Output: Phono outputs are designed specifically for turntables. They produce a phono-level signal, which is much lower in amplitude than a typical AUX-level signal. This is because vinyl records are encoded with a specific equalization curve (RIAA) that must be corrected during playback. Phono preamplifiers, also known as phono stages, are required to boost the signal and correct the frequency response.
- Line-Level Output: Some modern turntables, often labeled “turntables with built-in preamps,” come with line-level outputs. These are compatible with AUX inputs and don’t require an external phono preamplifier.
Connecting a Turntable to an AUX Input
- Using a Turntable with a Built-in Preamp: If your turntable has a built-in preamp and provides line-level outputs, connecting it to an AUX input is straightforward. Simply connect the turntable’s RCA cables to the RCA or 3.5mm jacks on the AUX input of your receiver or amplifier.
- Using an External Phono Preamp: If your turntable only has phono outputs, you’ll need an external phono preamplifier to boost the signal and correct the RIAA equalization. Once you have a phono preamp, follow these steps:
- Connect the turntable’s RCA cables to the phono preamp’s input.
- Connect the phono preamp’s output to the RCA or 3.5mm jacks on the AUX input of your audio equipment.
Considerations and Tips
When connecting a turntable to an AUX input, here are some important considerations and tips to keep in mind:
- Grounding: Most turntables have a ground wire to reduce interference and hum. Ensure that you connect this wire to the corresponding ground terminal on the phono preamp or the turntable if it’s a direct connection to an AUX input.
- Input Selection: On your amplifier or receiver, be sure to select the correct input source. AUX inputs are usually labeled as “AUX,” “Line In,” or something similar.
- Volume Levels: When connecting a turntable to an AUX input, make sure to set the volume at a reasonable level to prevent distortion and protect your speakers.
- Phono vs. Line-Level Switch: Some turntables with built-in preamps may have a switch to toggle between phono and line-level output. Make sure it’s set to line-level when connecting to an AUX input.
- Check Compatibility: Ensure that your turntable and audio equipment are compatible in terms of input/output levels. Mixing a phono-level signal with an AUX-level input without a preamp can result in very low volume and poor sound quality.
Conclusion
In summary, it is possible to connect a turntable to an AUX input, but the compatibility of your equipment and the type of outputs on your turntable are essential factors to consider. Whether your turntable has a built-in preamp or you use an external phono preamp, connecting it correctly can allow you to enjoy the warmth and nostalgia of vinyl records through your modern audio system. With the right setup and understanding, you can make the most of your vinyl collection in the digital age.
